A cluster randomized controlled trial and economic evaluation with a 12-month follow-up and with work department as the unit of randomization.
To evaluate the effectiveness of a prevention program for low back pain (LBP) in an occupational setting with an economic evaluation.
LBP accounts for high economic costs in Western societies. Little is known on the effectiveness and related costs and savings of prevention programs for LBP.
The study population consisted of workers in physically demanding jobs from 9 large companies located throughout The Netherlands. In each company, 2 comparable work units were randomly allocated, resulting in 18 clusters with 258 workers assigned to the intervention group and 231 workers to the control group.
Results in our study did not show significant differences in effects or costs savings of the program. Indirect costs related to work absence and productivity losses accounted for the majority (84%) of total costs due to LBP.
This study provides no evidence for the adoption of this worksite prevention program for LBP.
一项整群随机对照试验及经济评估，随访12个月，以工作部门作为随机分组单位。
通过经济评估，评价职业环境中一项腰痛（LBP）预防计划的有效性。
腰痛在西方社会造成高昂的经济成本。对于腰痛预防计划的有效性以及相关成本和节约情况，人们了解甚少。
研究人群包括来自荷兰各地9家大公司中从事体力要求较高工作的工人。在每家公司中，随机分配2个可比的工作单位，形成18个群组，258名工人被分配到干预组，231名工人被分配到对照组。
我们的研究结果未显示该计划在效果或成本节约方面存在显著差异。与缺勤和生产力损失相关的间接成本占腰痛总成本的大部分（84%）。
本研究没有为采用该工作场所腰痛预防计划提供证据。
